ROSOOE BEAN, OF SPRINGFIELD, OHIO.

PUMP.

SPECIFICATION forming part o Letters Patent No. 334,732, dated January 26, 1886.

Application filed Ma'y 28, 1885. Serial No. 166,976.

To all whom, z5 may concern.-

Be it known that I, ROSCOE BEAN, a citizen of the United States, residing in Springfield, in the county of Clark and State of Ohio, have invented certain new and usef'ul Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

My inventionrelates to an improvement in force and lift pumps, but refers more especially to that class of pumps that are designed for deep wells, my object being to produce a pump that is simple and compact in construction, not liable to get out of order, and which can be operated successfully in deep as well as shallow wells.

A further object of my invention is the novel construction and arrangement of the several parts of the-pump, whereby the entire internal working mechanism may readily be removed for repairs without the usual labor and inconvenience of removing the entire pump from the well.

Still another object of my invention is to construct a pump that is thoroughly antifreezing, dirt-proof, and which, from its compact and symmetrical construction, is especially adapted to drilled or other narrow wells.

The construction and operation of these several parts of my invention will be more readily understood by referring to the accompanying drawings, which form a part of this specilication.

Figure l represents a side elevation of my pump, showing a vertical section of that portion of it that is below the platform or wellcover, and which embraces the principal features ot' my invention. Fig. 2 is an enlarged view of a vertical section of the same. Fig. 3 is a transverse section ofl the pump at x x, showing a top plan view of the removable head and enlarged semicircularwater-way. Fig. 4 represents a side elevation of a vertical section, showing a modified construction of the inner cylinder and removable head.

.In the drawings, A represents the outer upper ease of the pump; B, the lower section of the case or pump-stock, which also forms an outer cylinder.

C represents the inner cylinder; D, the removable head; E, the enlarged water-way; F,

(No model.)

a section of the dischage-pipe or conduit; f, the curved section of same.

The lower section of the pump-stock or case B is from preference made smaller than section A, and is adapted to connect therewith, fitting inside of it. The upper end of section B is suitably constructed to form a seat or Vbearing for the removable head D, which is from preference made slightly tapering, and,

with its periphery provided with a suitable packing, is adapted to lit closelyin the seat or bearing formed in the upper end of case B. The enlarged water-way E is permanently connected with the removable head D, and is from preference made semicircular in form at its base, as shown in Fig. 3, thereby aii'ording ample space for the free and easy passage of water from the lower case, B, or outer cylinder. Converging to a cylindrical form ata1 x it is adapted to connect with conduit F or any ordinary discharge-pipe. The inner cylinder, C, is firmly connected to the removable head D, and may extend above it into ease A, if desired; but from preference I connect it to the lower side of the head D, and extend it downward into the outer cylinder, B, as shown in Figs. 1 and 2.

The removable head D is placed in position by being lowered from the top of the pump before cap N is putin place, and is tirmly held in place by the discharge-pipe F and stay rod or pipe Z, which are secured to the top of the pump. Stay-rod Z, as shown in Fig. l, may be dispensed with, if desired, and the removable head D held in place by the discharge- Ypipe F only, as shown in Fig. 2; but from preference I employ the rod or pipe also. The discharge-pipe F and stay-rod Z may be connected to and held down by cap N, or may be fastened to the top of the pump in any other desirable or suitable way.

Section A or the upper portion of the pumpstock is, as has been previously stated, preferably of greater internal diameter than the lower section. The advantage of this construction is obvious, as it will readily be seen that when it is desired to remove any portion cf the internal-working parts I have simply to remove cap N, and by loosening the fastenings of discharge-pipe F and 'stay rod or pipe Z the entire internal-working mechanism can be IOO readily and'easily withdrawn from the pump, inasmuch as the increased internal. diameter of case A permits of the withdrawal of head D and valve .Iwithout binding, thus avoiding unnecessary friction. The stay rod or pipe Z may be of any desired size, and being closed at the top, and passing through the removable head D, and open at the bottom will make it t0 serve as an air-chamber. The actuatingrod G is also from preference a hollow tube, closed at the top and provided with an open-v ing below the plunger I, which thus enables it to perform the functions of an ordinary airchamber, as well as that of an actuating-rod.

The inner cylinder, C, is adapted in diameter to receive half of the water that is lifted at one upward stroke of the valve J, the remainder passing up through the enlarged waterway E, and out at the discharge-pipe. The downward movement of the actuating-rod G (towhich is attached plunger I, as well as valve J) forces the water down and out of cylinder C, and drives it out of the dischargepipe also. Thus an unbroken flow of water is the result. It will be observed that under this construction the actuating-rod is not eneumbered with any packing-boxes through which it must pass. Therefore the friction is greatly lessened, and the ease of operating the pump is materially increased.

As shown in the drawings, the working parts of the pump are all placed at a suiicient distance belowthe platform or well-cover to prevent freezing, and in order to provide against the water freezing in the discharge-pipe an opening, c, as shown in Fig. l, is provided, whereby the water may drain back into the well, leaving the pipe empty.

Lever I-I and its supporting-standard may be of any desired form, and cap N may be secured to the top of case A in any desired or convenient manner.

Flange K may either be cast with the case A or secured to it by any suitable means, and is designed to rest upon the platform or wellcover, thus supporting the pump in its position.

Fig. 5 represents a modiiied construction of my pump, in which the enlarged semicircular water way E is dispensed with, and the conduit F extended down to and connected directly to the removable head D; but in order to employ this construction, the opening in head D must necessarily be ofless diameter than would permit the reception of cylinder C, as shown in Fig. 2; hence, the cylinder is dropped down and connected to the removable head D by means or" a contracted neck, as shown in Fig. Ai. The practical operation of this device is substantially the sameas Fig. 2.

y By conforming to the construction shown in Figs. l and 2, I have, first, a force-pump that is entirely without side openings or projections, thus adapting it to drilled or other very narrow wells; second,a vertical watenway that permits of the free discharge of water With the least Vpossible friction or obstruction; third, the entire internahworking mechanism easily and quickly removable without in 4an y Way disturbing or displacing the pump-stock; fourth, thoroughly antifreezing and dirtproof; iii'th, operated with ease in deep wells, and at the same time I have a most powerful force-pump, all parts of the device being so constructed that unnecessary friction is avoided. The action is direct and lwater-ways large, therefore I can operate the pump with the least possible loss of power. The whole is constructed and arranged with special reference to cheapness of construction, durability of parts, and ease of operation.

It is obvious that the practical utility of the removable head, and the discharge-pipe secured thereto and adapted to convey the water and act as a means of withdrawing the head, is not confined to use in connection with a pump in which a stock, as at A. is employed to support or suspend the pump beneath the platform; but these features may be used with equal advantage in pumps in which rods or tubes are used to support the pump proper. The same is true of the inner cylinder when combined with the removable head and the discharge-pipe.

I/Vhat I therefore now claim as new, and desire to secure by Letters Patent, is-

l. In a pump, the combination, with the removable head and the discharge-pipe secured thereto, of the outer cylinder communicating with the discharge-pipe, and the smaller cylinder within the outer cylinder and supported by said head.

2. In a force-pump, the combination, with the removable head, of the tubular air-chainber and the discharge-pipe, both secured thereto at their lower ends.

3. In a force-pump, the combination, with the removable head and the water-way secured thereto and enlarged at its point of connection therewith, of the discharge-pipe connected to the said water-way.

4. In a force-pump, the combination, with the removable head, of the inner cylinder secured thereto by an intervening neck or pipe of smaller diameter, whereby greater radial space between the edge of said neck and the periphery of the head is afforded for accommodation of the discharge-pipe.

In testimony whereof I have aiixed my signature in presence of two witnesses.
